osepp lcd display 16x2 manufacturer

The OSEPP 16 x 2 LCD Display and Keypad shield can plug directly onto the Arduino and Arduino compatible boards. The LCD panel displays characters in white with a blue backlit and can display up to two lines of 16 characters. The shield includes 6 momentary push button that can be used to implement a 5 buttons keypad including up, down, left, right and select function. The sixth push button brings out the Arduino�s reset button to the top of the shield.

The OSEPP 16 x 2 LCD Display and Keypad shield interfaces with the Arduino board using digital pin 4 to10 and analog pin 0. The contrast can be adjusted via a trim pot and the backlit can be turn on and off. The shield is 5V compatible.Mate with Arduino and Arduino compatible boards

This decision was based on the fact that I had a 16x2 display already lying around, and that I wanted to keep my GPIO pins free for the other parts I"m going to use for this project.

Note - this display is a relatively old model, and it isn"t important to use the exact model. You may have to look up a different set of Arduino drivers from the manufacturer if you are building this project on your own.

Therefore, I"ll need to set the code up to allow me to communicate back and forth between the Arduino and the Python script, sending messages to be displayed, and passing button inputs from the board back to Python.

So, let"s break down what"s happening here:I"m setting up the LCD display using the LiquidCrystal drivers, and assigning it to the pins that are currently wired to the display.

Next, the serialEvent is set up to listen to any messages coming in over the USB connection. It resets the screen and my string buffer, and then concatenates the whole message into a string. I then iterate through the characters and write them to the display, with bonus logic to handle a newline character to write to the second row.

The buttontest example gives us a good head start on this boilerplate, but I modified to change the logic to only send a message out on Serial when the most recent message changes. That looks a bit like this:// serial_lcd.pde
